The Cross of Jerusalem was shaped by La Monnaie de Paris from the lapel of the reverse of a coin called "un gros d'argent" (coin of about 5 grams, created by St. Louis after its seventh crusade) of the Frankish Kingdom of Jerusalem (XVth century). It represents a majestic cross of Jerusalem, flanked by four small crosses.

The back of the pendant is plain to be engraved and personnalized on request.
